CUSHION CONNECTION FOR VEHICLE CONSTRUCTION. l

Application led April 7,

In the United. States patent to Alfred F. Masury and August H. Leipert,No. 1,404,87 6 dated January 31, 1922, there is shown a cushionconnection for parts in vehicle construction, one of which parts is tobe supported by and connected to another part wherein non-metallicyielding material is carried with one of the parts and is availed of toengage the other part. In a preferred em- 10 bodiment disclosed in thatpatent the nonmetallic yielding material is rubber and is maintainedunder internal static pressure to increase its strength, resiliency andlasting qualities. In sprmg suspensions generally, and particularlywhere a Hotchkiss drive for the vehicle is availed of, one end of thespring is maintained relatively ixedwith respect to the chassis frame inorder that ydriving and braking forces ma be transmitted therethrough tothe vehicle. The present invention has for its object the provision of acushion connection particularly applicable as a connection and supportbetween the relatively fixed end of a vehicle leaf spring and the framewhich shall meet certain requirements of simplicity and economyl inmanufacture. To this end the housing wherein the yielding non-metallicmaterial engaging the end of the leaf spring is retained is formed ofpressed metal and the end of the leaf spring is turned up and perforatedfor the passage of a bolt vention also passing through the yieldingnon-metallic material and serving to retain oneA of the parts of thehousing in position to apply the desired degree of compression. Moreparticularly a` drum-shaped two part housing is provided, one of whichparts is formed with an aperture for the entrance of the s ring end andadapted to be secured by wel ing to a bracket carried with the vehlcleframe. In order that the 4invention may be clearly understood the samewill now be described more fully with reference to the accompanyingdrawings illustratin a preferred embodiment thereof in whic: v

longitudinal side frame member b of the ve- 4 hicle through theinstrumentality of the cushion connection according to the presentinyention. The end of the leaf sprin which is lntended to be retainedrelatively xed with respect tothe frame enters through an aperture cformed in the upper half c of a drumshaped housing divided into twoparts in a diametric plane land the other part of the housmg 'c2 servesas a cover member and is removably secured b means of a bolt d passing'diametrically t rough the housing at right angles to the plane ofjuncture. The

vmain housing portion c within which the posed within the housing issubstantially cylindrical outwardly and is formed with an angular recessf for the reception of the end a of the spring which is turned at ri htangles of the general longitudinal d-irect1on of the s ring in order toafford ample bearlng sur ace 'in the transmission of drivin and'brakingforces. To facilitate the posltionmg of the yielding non-metallicmaterial within the housing and also to contribute to the facility withwhich the block may be placed under internal static ressure 1t is formedwith a protruding port1on f2 adapted to be positioned within a recess caformed in the lower housing half c about the aperture c4 for the bolt d.The passage f* for the bolt formed in the yielding non-metallic materialis preferabl vcountersunk as at f", f' and f to facilitate t e entranceof' the bolt therein and also to afford space for the distortion of thenon-metallic material when under compression. Similarly'the recess f iscountersunk as at f8 where the-spring enters.l Simil'arly the recess fis enlarged as at f at its inner en'd to allow for Adistortion of thematerial.

In ,the interest of manufacture and assembly the aperture o throughwhich the spring enters the housing is formed with a fiarin mouth andthe fiange c thereof is also availe of as a part of a continuous seatfor theucoc. It is to be noted that the bolty Z holding the two partsyof` the' housing together lies in a plane disposed at an angle to therespec` tive planes of the forces of load and thrust impressed upon theconnection, while theline of'separation of the housing parts issimilarly .disposed at an angle thereto and is furthermore perpendicularto the axisgof the bolt. The load and Ithrust is thus mostadvantageously resisted.

By the construction described a cushion connection is provided for therelatively fixed end of a vehicle leaf spring which is convenient andinexpensive of manufacture, is readily assembled and aiords ample meansfor the transmission of driving and braking thrusts. l

Various modifications may beinade in the configuration and manner ofmanufacturing the cushion connection according to the present inventionand no limitation is intended by the foregoing phraseology orillustration exce t as indicated in the appended claims. f at I clainis: .v
